Hello ST Community teamThe pin F11 on the TFBGA216 figure (figure 4 of the AN4660) should be VDD and not VSS according to the products datasheets (for the STM32F469N and STM32F769Nx6). That should be rectified on the next doc revision. Best Regards.I...
I am trying to apply this configuration to my STM32H757 MCU where I am making a development board. here few things confuses me. 1. I have selected this configuration for better efficiency + noise performance. guide me if I am wrong2. What is the VDD ...
Hi I am looking into using STM32F446RCTx for my design, which includes 2 x USB FS 2.0 (1 x Host + 1 x Device). Hence need to provide an external HSE. I want to use an Oscillator, meaning I setup the HSE as "Bypass Clock Source" .With this setup I pla...
Hi Everybody1) There are some technical o specific reasons, that I was not able to find in the various documentations, to use external SMPS for VDDCORE insted of the internal one ?2) Working on NUCLEO-N675X0-Q, to configure various bridge for interna...
Hi everyone! hope you can help me. I have an issue on the STM32H7A3ZIT6.I already used the BKPRAM on other project, like the STM32H753 and I had no issue, work perfectly.So I don't understand why it is not OK, here below is what I do to test the BKPR...
Heyho,management asked me about a project involving 1 or 2 audio input channels at 32-bit / 200 kHz and - here's my knowledge almost zero - some "heavy & intense" DSP / FFT algorithms for real-time signal evaluation.We're already using the H723 .. H...
Hello everyone.How do I update the firmware via VCP on STM32F407VET6? Is it possible to do so? If so, what needs to be changed and added? Do I have to recreate the bootloader?I don't know where to start here.Thank you :)
Hi,I'm using an STM32H750XBH6 with an ISSI IS42S32400J-6BL, but the read/write operations keep failing.I’ve tried setting the CLK to 166 MHz / 120 MHz / 100 MHz / 50 MHz, but it still fails.When measuring with an oscilloscope, I found that the FMC_Dx...
Hi everyone . I have timer problem again. I use STM32G431KBT6. I'm using timers. timer 3 for pwm pulse direction servo motor and timer 8 for pwm speed control dc motor. But when start timer8 pwm, timer 3 is starting same time. What could be the reaso...
I have a question about PVD.I have this main.c file. My interrupt function void TM_PVD_Handler(uint8_t status) won't execute when the power goes off. Why? In this case, I'm sending a message to the UART to see if my computer recieves the message befo...
